The Marib campaign, also called Marib offensive (Arabic: جبهة مأرب), was a military campaign in the Yemeni civil war for the control of the Marib Governorate of Yemen. Fighting between the Houthi forces and factions of the Yemeni Army loyal to the Supreme Political Council on one side, and Yemeni Army units loyal to President Abdrabbuh Mansur Hadi and militiamen on the other side, has taken place since early 2015. Marib is rich in oil and gas resources and is a key strategic governorate because it connects the Houthi-controlled Sanaa and Alimi-controlled Hadhramaut governorates. On April 1, a United Nations sponsored two-month nationwide truce took place until October 2022, however the truce continued in practice.
